The lytic cycle of bacteriophage infection ends with?
The lytic cycle of bacteriophage infection ends with the lysis of the bacterial host cell. Once the phage has replicated its genetic material and assembled new viral particles, it produces enzymes that break down the bacterial cell wall. This rupture releases the newly formed phages into the environment, allowing them to infect other bacterial cells. Consequently, the lytic cycle results in the destruction of the host cell and the propagation of the phage.
The viral reproductive cycle in which a phage injects its DNA into a host cell and uses the cell's metabolic machinery to produce new phages which then causes the cell to rupture is called what cycle?
The viral reproductive cycle you are describing is called the lytic cycle. In this cycle, the phage hijacks the host cell's machinery to replicate itself, leading to the destruction of the host cell when it bursts open to release new phages.
The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cells chromosome is called the what cycle?
The viral reproductive cycle you are describing is called the lysogenic cycle. In this cycle, the viral DNA integrates into the host cell's chromosome, remaining dormant until it is triggered to enter the lytic cycle.
What are temperate phages?
Temperate phages are bacteriophages that can follow two replication pathways: lytic and lysogenic. In the lytic cycle, they infect a bacterial host and replicate rapidly, causing cell lysis. In the lysogenic cycle, they integrate their DNA into the host genome, replicating along with the host without causing immediate cell lysis.
Why bacillus anthracis susceptible to gamma phage?
Bacillus anthracis is susceptible to gamma phage because the phage has evolved to target and infect specific receptors on the surface of the bacterium. This interaction enables the gamma phage to inject its genetic material into the bacterium, hijacking its machinery to produce more phage particles and ultimately leading to the destruction of the bacterial cell.
What happens first when a phage infects a bacterial cell and is going to enter a lysogenic cycle?
it becomes a part of the bacterial DNA and it can be replicated into the daughter cells. this cycle doesn't harm the bacterial cell but it can change into the lysis cycle and kill the host cell
The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cells chromosome is called the?
motor cycle
The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cell's chromosome is called the cycle?
B) Lysogenic
How does the reproduction of HIV and lambda phage differ?
The Lambda Phage bacterial virus replicates itself whilst the HIV virus binds itself to existing cells and damages them. Lamba Phage increases with a "lysogenic" cycle, whilst the increase of HIV is known as "Lytic".
The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cell's chromosome is called the?
lysogenic

The lytic cycle of bacteriophage infection ends with the lysis of the bacterial host cell.

This rupture releases the newly formed phages into the environment, allowing them to infect other bacterial cells. Consequently, the lytic cycle results in the destruction of the host cell and the propagation of the phage.
When the bacteriophage DNA becomes part of the bacterial chromosome?
When bacteriophage DNA becomes integrated into the bacterial chromosome, it is known as lysogeny. The integrated phage DNA is called a prophage. During lysogeny, the bacteriophage DNA remains dormant, replicating along with the bacterial chromosome. Under certain conditions, such as stress, the prophage can become activated and enter the lytic cycle, leading to viral replication and cell lysis.
The viral reproductive cycle in which a phage injects its DNA into a host cell and uses the cell's metabolic machinery to produce new phages which then causes the cell to rupture is called what cycle?
The viral reproductive cycle you are describing is called the lytic cycle. In this cycle, the phage hijacks the host cell's machinery to replicate itself, leading to the destruction of the host cell when it bursts open to release new phages.
In What process does a phage kill its host?
A phage kills its host through the lytic cycle, where it attaches to the bacterial cell, injects its genetic material, and hijacks the host's cellular machinery to replicate its own components. This leads to the assembly of new phage particles within the host. Eventually, the host cell becomes overwhelmed and lyses, or breaks open, releasing the newly formed phages to infect other cells. This process results in the destruction of the host bacterium.
When a T2 bacteriophage infects an E. coli cell what part of the phage enters the bacterial cytoplasm?
the whole phage
What is a latent phage?
A latent phage, also known as a temperate phage, is a type of bacteriophage that can enter a dormant state within a bacterial host. Instead of immediately replicating and causing cell lysis, the phage integrates its genetic material into the host's genome, becoming a prophage. This latent phase allows the phage to be replicated along with the host's DNA during cell division, potentially reactivating under certain conditions to enter the lytic cycle. This ability to alternate between lytic and lysogenic cycles gives latent phages a unique role in bacterial evolution and ecology.
The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cells chromosome is called the what cycle?
The viral reproductive cycle you are describing is called the lysogenic cycle. In this cycle, the viral DNA integrates into the host cell's chromosome, remaining dormant until it is triggered to enter the lytic cycle.
